Prototype perches are back from the platers and we have a set built up to go on our first 1M tester later this week. After we verify the install on that car I'll contact the local guys on my list for the second spot.

We went with red. Seems to be our color.

At crazy angles they still have clearance between the unmolested bolt head and perch and they have the same perch height as the OEM perches.

Here's the perch with the OEM rubber isolator on it. Shame to cover up all that red aluminum.

Are these modular in the sense that they can later be converted to work with a different coilover/damper, like Motion Control Suspension?

Yes. They are fully modular. With a change of spring perch and adapter spools they can fit almost any aftermarket strut. 60mm and 2.5" perches and spools cost $75 or $100 per pair depending on the need for extended top nuts.

Great to hear! Pending the release date of these, I might buy a set for my E46 and E90 at the same time ;-)
